    • Abstract
  • The CoCrFeNiCuTix(x = 0.25, , 0.50, 0.75, 1.00 by molar) high-entropy alloys (HEAs) were prepared by vacuum hot-pressing sintering in this paper. The effects of Ti contents on the microstructure and corrosion resistance of the CoCrFeNiCuTix HEAs were investigated and analyzed by optical microscope (OM), X-ray diffractometer (XRD), scanning electron microscope (SEM), HVS-1000B digital microhardness tester, and electrochemical workstation. The results show that the CoCrFeNiCuTix HEAs with different Ti contents by molar have the face-centeredcubic phase structure with the dendritic crystal microstructures. With the increase of Ti content, the dendritic structure declines in numbers, and the hardness of CoCrFeNiCuTix HEAs increases first and then decreases; the microhardness of the prepared HEAs reaches the maximum up to HV 755 at x=0.5. The self-corrosion potential of the prepared HEAs is positive to that of 45# steel; with the increase of Ti content by molar, the self-corrosion potential of the prepared HEAs increases first and then decrease, and the best corrosion resistance is obtained at x=0.5.
